ABSTRACT:
Apparatus is provided for digital printing images in annular-radial coordinates onto discs having an axis of rotation, the printing to occur between an inner radius R.sub.1 of the disc and an outer radius R.sub.2 of the disk. The Apparatus includes a linear printhead array extending radially of the disc at least between inner radius R.sub.1 and outer radius R.sub.2 ; and a drive adapted to rotate the disc about the axis while the printhead is imagewise addressed to create an imaged area that is symmetric to the center of the disc. The drive is adapted to rotate the disc at an annular velocity such that the spatial resolution of the printed image along the outer edge of the image is the same as that of an original image being printed. The image area may be continuous about substantially the entire annular surface of the disc or divided into discrete sections to be printed in associated tiles located on the disc such that:
